Research ArticleOpen accessIn the abstractRocks with Asbestos: Risk Evaluation by Means of an Abrasion TestBellopede Rossana, Clerici Carlo, Marini Paola, Zanetti GiovannaNaturally occurring asbestos and asbestiform minerals can be found in metamorphic rocks and in the soil of the alluvial plains. Problem statement: The definition of the "free-asbestos rock" and the limit to consider a rock or a soil safe is still a controversial issue. American and European laws did not present any method to define the hazard of the green … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Oct 2009 · 7,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of the Work Environment on the Safety Performance and Safety Management Practices: Its Influence on the Attitudes of Nurses in the Jordanian HospitalsAbdallah Ashour, Zuraida HassanThis study employs an integrated model, combining management practices studies and social theories, to examine the safety management practices and behavioural safety of Jordanian nurses from public hospitals. Our research employs Partial Least Squares (PLS-SEM) regression analysis to test the model. Hedonic value and utilitarian value are proposed as first-order reflective indicators of second-order formative value construct. The role of … …American Journal of Applied Sciences, Vol. 16, Issue 11 · 24 Dec 2019 · 7,612 accessesView PDFCite
Research ArticleOpen accessIn the abstractYeast Immobilization on Peanut Hulls for Potential Application in Beer FermentationWaldir D. Estela-Escalante, Sergio Rosales-Mendoza, Mario Moscosa-SantillánThe potential of using peanut hulls as support material for immobilization of yeast cells during beer fermentation was evaluated. After treatment of peanut hulls with 0.5% (w/v) NaOH, FTIR analysis revealed an important change on its chemical composition. For instance, the proportion of lignin decreased and as a result the adsorption of yeast cells onto the support material during fermentation … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 22 Jul 2019 · 8,378 accessesView PDFCite
Research ArticleOpen accessIn the abstractLiquid Crystalline Polymers Compatibilization and Adhesion Enhancement by Reactive Blending in Post-Consumers PET’sAversa Raffaella, Apicella AntonioA method for PET mechanical properties enhancement by reactive blending with HBA/HNA Liquid Crystalline Polymers for in situ highly fibrillar composites preparation is presented. LCP/PET blends were reactive extruded in presence of Pyromellitic Di-Anhydride (PMDA) and then characterized by Differential Scanning Calorimetry, Thermally Stimulated Currents and tensile mechanical properties. The formation of specific macromolecular structures, where the PET, the LCP … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 17 Jun 2016 · 8,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurface Modification of Polystyrene Beads by Ultraviolet/Ozone Treatment and its Effect on Gelatin CoatingA. N. Yusilawati, M. Maizirwan, M. S. Hamzah et al.Problem statement: Polystyrene failed to provide any reactive functionality of surface hydrophilicity that is capable of binding proteins. It is known that polystyrene must be chemically modified to make its surface amenable to covalent crosslinking with protein. Approach: The aim of this study was to investigate the effects of UV/ozone treatment on gelatin coating. The surfaces of microsize polystyrene beads … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandardization of Metal-Based Herbal MedicinesArun Sudha, V. S. Murty, T. S. ChandraProblem statement: Standardization of herbal drugs is a burning topic in herbal drug industry today. Standardization is difficult because they are usually mixtures of many constituents and the active principle in most cases is unknown. However it is possible to generate a physico-chemical fingerprint for the standardization of these drugs with reference to authentic drugs, for monitoring variation between preparations … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,906 accessesView PDFCite

Review ArticleOpen accessIn the abstractContinuous Flow Synthesis of Zeolite-A from Coal Fly Ash Utilizing Microwave Irradiation with Recycled Liquid StreamSalman Bukhari, Sohrab RohaniCoal Fly Ash (CFA) was converted to zeolite using continuous microwave reactors while minimizing the wastewater produced during the zeolitization process. At bench scale, a continuous flow tubular microwave reactor was used to explore the effect of microwave irradiation on the crystallinity of the product. The waste water was reused in consecutive runs and Inductively Coupled Plasma (ICP) analysis was … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 19 Jun 2017 · 7,240 accessesView PDFCite
